A REVIEW OF THE MYSIDACEA 29 



4912, 6 specimens; 4913, 7 specimens; 4914, 2 males, 1 female, and 

 1 immature, 19 to 44 mm. ; 4915, 1 male and 1 female, 37 to 39 mm. 

 Philippine Islands: Albatross stations 5238, 1 male, 38 mm.; 5364, 

 1 male, 44 mm. ; 5438, 1 female, 49 mm. ; 5618, 1 male, 45 mm., 1 female, 

 43 mm. ; 5628, 1 female, 42 mm. ; 5630, 1 female, 49 mm. Hawaiian 

 Islands: Ortmann (1906) identified material from the following Al- 

 batross stations: 3467*, 3473*, 3475*, 3824*, 3826*, 3907*, 3908*, 3909*, 

 3911*, 3925*, 4105*, 4106*, 4107*. The National Museum collection 

 contains one specimen, a male, 35 mm., without locality. 



Distribution. — This species is not known from the coasts of Amer- 

 ica. It has been recorded from the Philippine Islands, 255 fathoms 

 (Sars), from several localities in the neighborhood of Hawaii, 222 to 

 498 fathoms (Ortmann), from the waters of the East Indian Archi- 

 pelago, 521 to 694 fathoms (Hansen), and by Shiino (1937) from off 

 Japan. The specimens in this collection are from two sets of locali- 

 ties, one in the waters southwest of Japan, 391 to 434 fathoms, and 

 the other in the waters of the Philippine Islands. The species appears 

 to be confined to the western part of the Pacific Ocean and to waters 

 of comparatively shallow depth, not exceeding 500 fathoms. In these 

 waters it is an abundant species. 



Remarks. — I have nothing to add to the descriptions of Sars and 

 Ortmann, with which these specimens are in complete agreement. 

 None of the specimens that I have examined is as large as those 

 recorded by Hansen.
